Abstract
Viene proposto un sistema di guarnizioni per una valvola a più vie, particolarmente pneumatica. Esso comprende un manicotto di sostegno (4) che presenta sia nell'ambito della sua periferia esterna (11) sia anche nell'ambito della sua periferia interna (13) più incavi di sostegno periferici (10, 12), assialmente distanziati. Negli incavi di sostegno (10, 12) sono tenuti degli elementi di tenuta (5, 6), perlomeno gli elementi di tenuta interni (5) essendo formati da materiale per guarnizioni colato direttamente negli assegnati incavi di sostegno (12). Inoltre viene indicato un procedimento per la semplice fabbricazione di un tale sistema di guarnizioni.A system of seals is proposed for a multi-way valve, particularly pneumatic. It comprises a support sleeve (4) which has both peripherally spaced support grooves (10, 12) both within its external periphery (11) and also within its internal periphery (13). Sealing elements (5, 6) are kept in the support grooves (10, 12), at least the internal sealing elements (5) being formed from gasket material poured directly into the assigned support grooves (12). Furthermore, a method for the simple manufacture of such a system of seals is indicated.
